I've tried it various ways, but this is the one I'm currently using:

  <extension name="DIALTONE">
    <condition field="destination_number" expression="^DIALTONE$">
      <action application="socket" data="127.0.0.1:8084 async full"/>
    </condition>
  </extension>

Using nc on port 8084, I get the DTMF events in real time before I call gentones--and after it finishes--but during the tone the DTMF events appear to be queued and only delivered once the gentones completes.

For example (long responses truncated for clarity)

$ nc -v -l 127.0.0.1 8084
Connection from 127.0.0.1 port 8084 [tcp/*] accepted
connect
